#Technology Detects Lingering Cancer cells During Breast Surgery Many patients undergoing lumpectomy surgery at NYU Langone Medical center for the removal of an early detected breast tumor the surgical option of choice for this diagnosis

--are benefitting from new intra-operative technology that detects microscopic amounts of cancer cells on removed tumor tissue not visible during or following surgical intervention.

The Division of Breast Surgery at NYU Langone was the first in New york city to utilize Marginprobe for early stage breast cancer.

the surgeon excises additional tissue from the surgical site to ensure that no additional cancer cells remain. he greatest benefit of Marginprobe is that we can perform this additional tissue removal during a patient initial surgery,

and frustration of additional follow-up surgery, said Freya Schnabel, MD, Director of Breast Surgery at NYU Langone.

Marginprobe was the subject of a major multi-institutional retrospective study led by Dr. Schnabel and published in the March 2014 edition in Annals of Surgical Oncology.

This, in turn, improves the rate of a completely successful lumpectomy with no additional follow-up surgery required.

Most patients will undergo some form of post-surgical treatment, either chemotherapy or radiation therapy, or a combination of the two.

Marginprobe greatest benefit is that it provides added assurance to both the surgeon and the patient that all cancer cells are removed during the initial surgery. t is critically important to spare patients the additional burden of re-excision procedures

and the time that is lost from work and family. Marginprobe helps us achieve that. i

you need to have surgery to replace it. Power is always a challenge. The innovation is a flexible piezoelectric layer sandwiched between biocompatible plastic.

a new generation of surgical implants A new manufacturing process for surgical implants will reduce the recovery time associated with traditional implants.

which can cause post-surgery complications. In addition, patients often have long waiting times for implants

Efficiency by design The new technology reduces waiting times and post-surgery complications, saving on care costs and helping patients resume their normal lives more quickly.

The faster surgery and shorter hospitalisation times also reduce the impact on patientslives. Manufacturing costs are reduced, too.

and stop epileptic attacks without drugs and without major brain surgery. To the 50 million people worldwide who suffer from epileptic seizures a chronic neurobiological disorder this simple plan could transform their lives.

there is no need to open up the bone during surgery.""This can dramatically reduce complications (infections, intracerebral bleeding, etc.

"And shorter, less-complex surgeries usually lead to faster postoperative recovery in general, "he adds. Patents have been filed for the TSPUMMNRPS device,

In particular, polysulfone is of interest in the biohealth field in the development of medical/surgical equipment:

#A robot in mind It a new kind of robot, designed for some of the most delicate operations a surgeon can perform.

his is a robotic system for assisting a surgeon during neurosurgery operations. It has been designed for the insertion of instruments like biopsy probes or electrodes for deep brain stimulation through small holes in the head of the patient.

It a new kind of robot, designed for some of the most delicate operations a surgeon can perform.

and is far steadier than a surgeon hand. And that a big help: o maintain a specific orientation

Neurosurgeon Francesco Cardinale is a specialist in epilepsy surgery. He helped the robot engineers at Politecnico di Milano understand what doctors really need.

One of the system innovative features is the feedback from the robot to the surgeon via the hand-held controller.

he surgeon can control the movements of the active robot using an instrument like that,

The robot feedback is amplified to help the surgeon feel his way around the brain. So what kind of operation could be perfomed with this type of robot?

The robot, developed within the EU Robocast project, is a year away from surgical trials.

Another area of application is medical surgery. A doctor could transfer data to and from a computer just by wearing an electronic bracelet and belt.

A 70 year old patient of the Southampton Hospital in the UK, Anthony Batchelor, has already been subjected to triple bypass surgery,

Pre-surgery measurements are a very important part of the whole treatment; physiological responses like blood pressure or respiratory rate are analysed in comparison to the physical activities of the patient.

"said Eugene S. Flamm, chairman of the department of neurosurgery at Montefiore Medical center and Albert Einstein College of Medicine."

##The ramifications of the work presented in the PNAS paper are tremendous with respect to tissue grafts used in surgery as well as new tissues fabricated using the principles of tissue engineering##says Kyriacos A. Athanasiou a professor of biomedical engineering and orthopedic surgery and chair

#Brain surgery robot would go through the cheek Vanderbilt University Posted by David Salisbury-VU on October 16 2014for people with severe epilepsy treatment can mean drilling through the skull deep into the brain

In addition the needle is inserted in tiny millimeter steps so the surgeon can track its position by taking successive MRI scans.

According to project leader Eric Barth associate professor of mechanical engineering the next stage in the surgical robot s development is testing it with cadavers.

'##At the same time Robert Webster associate professor of mechanical engineering had developed a system of steerable surgical needles.####The idea for this came about when Eric and

The engineers identified epilepsy surgery as an ideal high-impact application through discussions with Joseph Neimat associate professor of neurological surgery.

Comber and Barth shadowed Neimat through brain surgeries to understand how their device would work in practice.##

and unlimited access would make surgeries minimally invasive. We could do a dramatic surgery with nothing more than a needle stick to the cheek.##

##The engineers have designed the system so that much of it can be made using 3d printing in order to keep the price low.

-like particles could give doctors a new option for curbing surgical bleeding and addressing certain blood clotting disorders without the need for transfusions of natural platelets.

Researchers also tested blood from infants that had undergone open heart surgery which requires that their blood be diluted reducing its clotting ability.

But the researchers believe the particles could also reduce the need for platelet transfusions in patients undergoing chemotherapy or bypass surgery and in those with certain blood disorders.##

Even when a neurosurgeon removes the bulk of the tumor, small invasive areas escape detection and keep growing, unchecked by the body.

surgical removal of the ridge or ring below the aortic valve is one option for improving the child health.

many women with DCIS are reluctant to take oral tamoxifen after being treated with breast-saving surgery

says lead author Seema Khan, professor of surgery and professor of cancer research at Northwestern University Feinberg School of medicine.

Women who have completed surgery and radiation are given oral tamoxifen for five years to reduce the risk of the DCIS recurring at the same place

#Test eliminates need for second thyroid surgery A new test increases the odds by 30 percent that people with thyroid cancer will undergo the correct initial surgery. efore this test,

says Linwah Yip, assistant professor of surgery in the University of Pittsburgh School of medicine. Yip says without the test a second surgery to remove the thyroid was required often

if the portion removed during the first surgery came back positive for cancer. he molecular testing panel now bypasses that initial surgery,

allowing us to go right to fully removing the cancer with one initial surgery. This reduces risk

and stress to the patient, as well as recovery time and costs, adds Yip, lead author of the study published in the Annals of Surgery.

Cancer in the thyroid, which is located in the dam applearea of the neck, is now the fifth most common cancer diagnosed in women.

which is a surgical operation to remove half of the thyroid, is needed then to diagnose or rule out thyroid cancer.

In the case of a postoperative cancer diagnosis, a second surgery is required to remove the rest of the thyroid.

says Robert Koenekoop, professor of human genetics, pediatric surgery, and ophthalmology at Mcgill University. t is giving hope to many patients who suffer from this devastating retinal degeneration.

The sensor would be embedded with an artificial lens during cataract surgery and would detect pressure changes instantaneously,

If you can fit this sensor device into an intraocular lens implant during cataract surgery it won require any further surgery for patients.

The research team wanted to find an easy way to measure eye pressure for management of glaucoma,

Shen says. e want every surgeon who does cataract surgeries to be able to use this.

The team has tested successfully the sensing device embedded in the same flexible silicon material that used to create artificial lenses in cataract surgeries.

so it seems a natural pairing to place a pressure monitoring device in a new lens during cataract surgery.

and later removed via surgery. What if the camera could be created from biodegradable material and powered by an edible battery?

This takes the surgery requirement out of the equation, making for a much more comfortable patient.

Currently, the only way to change the batteries in these implants is through surgery. The edible battery might reduce the amount of surgeries required as its use is less invasive.

and their internal structures can someday be printed 3d for#surgical purposes. According to Martin even a rapid printing process didn t hamper the research team s results:##

Cells used in this sort of medical 3d printing will be grown to perfectly match those of the patient prior to surgery.

The process could also lead to other neural repair surgeries, possibly even including damaged nerve cells and spinal chord injuries.

Personally I am impressed by the maxillofacial surgeon who is using Mcor 3d printing to create surgical guides,

since researchers are limited currently at being able to predict a pacemaker effect on a patient before surgery, for example.

or perhaps even weakness following surgery. At a biological level, the stem cells that repair muscle damage lose their ability with age to generate new muscle fibers.

The same basic process could lay the groundwork for helping human patients heal after surgery

#High-tech glasses help surgeons see cancer The glasses are designed to make it easy for surgeons to differentiate cancerous cells from healthy cells.

Researchers at the Washington University School of medicine have developed high-tech eyewear that helps surgeons detect cancer cells, which glow blue

The special glasses are designed to make it easy for surgeons to differentiate cancerous cells from healthy cells allowing surgeons to make sure no cancer cells are left during surgery.

The usual procedure for surgery requires doctors to remove tumors and neighboring tissue which may or may not have cancer cells.

a second surgery is recommended usually to remove additional tissue that is also tested for the presence of cancer.

but it has already been used during surgery at the Alvin J. Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of medicine.

and surgeons sometimes replace the lens. But now, a team of scientists and ophthalmologists has tested a solution in dogs that may be able to dissolve the cataract right out of the eye lens.

Coming up with a solution other than surgery has been tough. Scientists have been hunting for years for mutations in crystallin proteins that might offer new insights

You'll see new applications in the ER in surgery with telehealth in remote communities and even in ambulances.

#Mini robot space surgeon to climb inside astronauts It could one day answer the prayers of astronauts who need surgery in deep space.

The miniature surgeon slides into the body through an incision in the belly button. Once inside the abdominal cavity which has been filled with inert gas to make room for it to work the robot can remove an ailing appendix, cut pieces from a diseased colon or repair a perforated gastric ulcer.

the surgery bot will perform a set of exercises to demonstrate its dexterity, such as manipulating rubber bands and other inanimate objects.

despite surgical attempts to remove them and for leading to a dire prognosis for patients.

But scientists are developing a new way to try to root out malignant cells during surgery so fewer

Surgical removal is one of the main weapons doctors have to treat brain tumors. The problem is that currently there's no way to know

The techniques surgeons have at their disposal today are not accurate enough to identify all the cells that need to be excised.
